Abstract: PURPOSE:To enhance a body washing effect in strengthening the rigid force of a brush material as well as to prevent any possible washing scratch due to the brush material and damage to a car body from occurring. CONSTITUTION:Multiple stripe water-holding grooves 3a, 3b holding water and a detergent are formed parallelly on the surface of strip brush material 1, while a tip of the brush material 1 is cut off in a bottom part of the water- holding groove 3b, dividing it into plural pieces of elements 2, while each tip of these elements 2 is further subdivided into pieces.
